When calibrating the PeCOD, the final step of the QC regime is to complete a QC Check on the pre-mixed calibrant solution. This will analyze the COD value of the pre-mixed calibrant solution to [...]

MANTECH’s recommended passing criteria varies for each colour range. The image below outlines the recommended criteria for each range.    

The acceptable range for MANTECH’s pre-mixed secondary standards is ±20%.

MANTECH Pro Software requires at least 4 USB cables on the computer. This is not including the computer’s mouse or keyboard. When required, the system will include a 4-port USB hub. Please [...]

To learn how to calculate Seed Correction and BOD, please refer to this document. In BOD Pro, two separate values for Seed Correction Factor are stored along with the Run; one is referred to as [...]

BOD indicates the amount of putrescible organic matter present in water. Therefore, a low BOD is an indicator of good quality water, while a high BOD indicates polluted water. Dissolved oxygen [...]

Higher COD levels mean a greater amount of oxidizable organic material in the sample, which will reduce dissolved oxygen (DO) levels. A reduction in DO can lead to anaerobic conditions, which is [...]

COD increases as the concentration of organic material increases. It also increases if inorganic compounds susceptible to oxidation by the oxidant (typically dichromate) are present. Water with [...]

BOD can also be defined as the amount of oxygen required by the micro-organisms in the stabilization of organic matter. The results are generally expressed as the amount of oxygen taken by one [...]
